Hi all,

Just bought another LG IPS234v, Here's the current setup:

  • Mini display to HDMI
  • HDMI to HDMI
  • DVI to DVI

For the life of me I can't get the third display to work with the other two, i can swap them around. I can't even enable it in the Windows resolution panel.
 
I can't get all three working at the same time, the display port one doesn't work. However, if I using the "Exchange Display" it swaps and the HDMI display turns off.
 
I've got the MSI R7850 Twin Frozr III. Is that what causes it to specifically disallow three displays simultaneously? As I said above I can get either of them working with the DVI to DVI.

The third monitor MUST be connected by an active DP to DVI/HDMI adaptor* OR have a native DP input.

*DP to VGA also works as its effectively active.

Would that Mini DP -> VGA work without any noticeable display issues? I could pop to the Apple store and have one now rather than waiting till Monday if that was the case.

Theorectically it should work although I have never tried one of the adaptors personally so I can't comment on display issues.
 
I wouldn't use the DP-VGA adaptor. There will be a noticeable degradation in image quality. You might not notice it in isolation but next to two other screens, there will be a difference.

Just get an active DP-DVI adaptor and you'll be good to go.
 
I'm using an active dp to DVI and I cant tell any difference when sat next to my other screens. Cant comment on the A-DP to VGA though.
